IsA - Operator (Derivation comparison)

Concerns

The operator's explanation is that a class structure is created in which a class "Mercedes" is derived from a class "Car".

Example

V1 := "Mercedes" IsA "Car"

Result:

V1 contains the value True (-1)

Declaration:

The IsA operator checks whether the Mercedes class is derived from the Car class or whether the Car class itself is the one.
